Wireless communication method and communication device

Abstract

A wireless communication method includes: transmitting, by a second station (STA), first indication information, wherein the first indication information is used to indicate that the second STA comprises low-latency traffic to be transmitted.

What is claimed is: 
     
         1 . A wireless communication method, comprising:
 transmitting, by a second station (STA), first indication information, wherein the first indication information is used to indicate that the second STA comprises low-latency traffic to be transmitted.   
     
     
         2 . The method according to  claim 1 , wherein the second STA comprises a plurality of STAs, and some or all of the plurality of STAs transmit same first indication information. 
     
     
         3 . The method according to  claim 2 , wherein some or all of the plurality of STAs transmit the same first indication information via Clear-to-Send (CTS) frames. 
     
     
         4 . The method according to  claim 3 , wherein the CTS frames are transmitted using a specific transmission rate and/or a specific modulation and coding scheme (MCS). 
     
     
         5 . The method according to  claim 4 , wherein PHY protocol data units (PPDUs) carrying the CTS frames transmitted by the plurality of STAs align at an end of the PPDUs. 
     
     
         6 . The method according to  claim 2 , wherein in a case where the first indication information is carried in a data field of a PPDU, scrambler seeds of data fields of different PPDUs transmitted by different STAs are consistent. 
     
     
         7 . The method according to  claim 6 , wherein the scrambling seeds of the data fields are notified by an access point (AP) in a beacon frame and/or a newly defined action frame, or are predefined. 
     
     
         8 . The method according to  claim 1 , wherein a network to which the second STA belongs further includes a first STA, and delay-sensitive transmission priority mode corresponding to the first STA is enabled by the first STA and notified to an AP. 
     
     
         9 . The method according to  claim 8 , wherein the second STA acquires that the AP has enabled the delay-sensitive transmission priority mode via at least one of following frames: a beacon frame, a probe response frame, an association response frame or a reassociation response frame. 
     
     
         10 . A second station (STA), comprising a memory and a processor, wherein the memory is configured to store a program, and the processor is configured to invoke the program stored in the memory, to cause the second STA to perform:
 transmitting first indication information, wherein the first indication information is used to indicate that the second STA comprises low-latency traffic to be transmitted.   
     
     
         11 . The second STA according to  claim 10 , wherein the second STA comprises a plurality of STAs, and some or all of the plurality of STAs transmit same first indication information. 
     
     
         12 . The second STA according to  claim 11 , wherein some or all of the plurality of STAs transmit the same first indication information via Clear-to-Send (CTS) frames. 
     
     
         13 . The second STA according to  claim 12 , wherein the CTS frames are transmitted using a specific transmission rate and/or a specific modulation and coding scheme (MCS). 
     
     
         14 . The second STA according to  claim 13 , wherein PHY protocol data units (PPDUs) carrying the CTS frames transmitted by the plurality of STAs align at an end of the PPDUs. 
     
     
         15 . The second STA according to  claim 11 , wherein in a case where the first indication information is carried in a data field of a PPDU, scrambler seeds of data fields of different PPDUs transmitted by different STAs are consistent. 
     
     
         16 . The second STA according to  claim 15 , wherein the scrambling seeds of the data fields are notified by an access point (AP) in a beacon frame and/or a newly defined action frame, or are predefined. 
     
     
         17 . The second STA according to  claim 10 , wherein a network in which the second STA belongs further includes a first STA, and delay-sensitive transmission priority mode corresponding to the first STA is enabled by the first STA and notified to an AP. 
     
     
         18 . The second STA according to  claim 17 , wherein the second STA acquires that the AP has enabled the delay-sensitive transmission priority mode via at least one of following frames: a beacon frame, a probe response frame, an association response frame or a reassociation response frame. 
     
     
         19 . A non-transitory computer-readable storage medium, having a program stored thereon, wherein the program causes a computer to perform:
 transmitting first indication information, wherein the first indication information is used to indicate that the second STA comprises low-latency traffic to be transmitted.   
     
     
         20 . The non-transitory computer-readable storage medium according to  claim 19 , wherein the second STA comprises a plurality of STAs, and some or all of the plurality of STAs transmit same first indication information.
